Inteltek manufactures fagor dros for increasing the productivity of grinders and guarantee high accuracy of the machines. They have four digital inputs used as emergency input and for resetting the axes. It is possible to control the grinding levels on the vertical axis and travel limits on the other axes. The grinding axis can be displayed continuously or only display the lowest position reached. The wheel dressing operation can be automatically compensated, as two feedback axes can be combined into a single axis display [except with the nv 10e]. The value of each level can be changed, even while within the grinding process, accessing the value directly from the keyboard. If the machine does not use all the operating levels, these can be deactivated. While grinding, the signals can be left in a non-active state, so that the electrode can be calibrated or replaced. It is possible to operate in radius or diameter, independently for each axis. In order to prevent the output signals and the display itself from constantly flickering, a hysteresis zone can be defined, within which any movement is not reflected in the display nor in the state of the outputs. In order to prevent the final drop due to the weight of the grinding wheel from making the finishing position lower than desired, the signals, may be programmed to be triggered at a distance prior to the position programmed.
